How to Draw a CCD from Code

How to Draw a CD from Code Suppose you want to understand a new component. What other components do you need to understand first? The main purpose of a component coupling diagram (CD) is to show you exactly this information. How do you start from the code to be understood, such as that in Figure 2, and produce a CD, such as that of Figure 1, which concisely summarizes the intercomponent dependencies of interest? The purpose of this document is

to demonstrate that proces, which could be automated by a tool. Many tools of this sort are available to draw UML clas diagrams, for example—another notation for depicting dependency information. There are six steps involved in drawing a CD from Resolve/C+ code, of which only the highlighted portion is relevant from the standpoint of a CD. These steps are ilustrated below in piece-by-piece construction of the example CD of Figure 1, which shows al the dependencies to al the components that you need to understand in order to understand Queue_Sort_1.
